The energy data from the US Dept of Energy Energy Information Administration State Energy Data System
were used to measure and compare the energy conservation performance of the buildings sectors
(residential and commercial combined) of each state for 2004 as a baseline year.
The report available from this page presents results for each state buildings sector for 2009
using the 2004 baseline scoring model.
Most state scores went up, indicating increasing energy conservation of buildings energy.
